Application led July 17, 1915, ISerial lo. .Renewed lecembe To all whom imag concern: "l y y Be it known that 1, Moniiis WonxsMAN, a citizen of the United `States,residing in the borough of Manhattan, city, county, and

State of New Yorin haveyinvented Icertain .j new and useful lmprovements` in Motory where the driving strain occurs, d the point of connection with the lars, of which the following is a specificaN tion.

My invention relates in general to motor cars, and especially to that type of motor cars comprising a detachable car .body` and frame for motor cycles. Side cars, for motor cycles have been employed to some extent, but they are subject to objectionable strains. y y y My invention relates particularly to a trailer car attachment for motor cycles.

The invention is illustrated inthe accompanying drawings, in which- Figure 1 is aside elevation of the assembled device; 1 y y Fig. `2 is a top plan view of the frame, with the body removed; y

Fig. 3 isa side elevation thereof with a portion of the car bodyin place, and

Fig. 4 is a transverse vertical section taken on the line 4 4 of Fig. 2.

Referring in detail to said drawings, 10

car body `indicates in general a motor cycle having a rear frame 1l, 12, from which the rear wheel and axle is removed. The rear wheelaxle is substituted by a hub 13, bearing the two chain drives 14, 15, for applyingpower to the hub and the chain drive 16, for `transmitting power from the hub to the trailer body attachment to be described. The hub 13 is mounted on an axle 17, whiclilias extension pieces 18, 19, screwed thereon against` the faces of the rear frame, as `illustrated clearly in Figs. 2 and 4.

The car bodyis `indicated at 20 and is mounted upon a frame which comprises in` general the double side bars21 and rear cross bar 22. The rear cross bar 22 is provided with shock absorbers 23, to which the car body is secured through the posts 24 and` clevis 25 (see Fig. 3). The forward" portion of the car body is pivoted to the rear frame 11 at theclamp 26 (Figs. 1 and 3). This are.

rangement provides for relative motion between the car body 20 and the frame. The car body frame is secured to therear frame 0f the motor cycle by means ofbars or rods `27, 28, the rod 27 being clamped firmly against the rear frame 11 of the motor cycle by the plates 29, 30, whereas the `bar 28 `clutch mechanism 50, 51. `journaled in bearin cles "7,.1913. sensi Nb. 265,790.,

frame portion`12 ofthe motor cycle. Bar 27 isv `secured to the inner. faceof side ,barclamps 31, 32, while bar 28 is secured tothe outer fece of` Side hardships. 33, 34. Inorder to stiften and reinforce the frame namely, at chain and sprocket drive 16, I provide a truss frame `extending across the car body frame proper.

Referring to Figs. 2, 3 and 4, it willbe seen that the axle extensions 1819-are mounted in side bar clamps 35, 36 and 37, 88. These clamps are bolted `together against the double side bars 21 and have depending ears 39 within which is bolted the truss bar 40, which extends across the frame. The truss bar 40 is connected at intermediate points with the rear frame of the motor cycle by means of the turn buckles 41, as shown clearly in Fig. 4.

Immediately behind the side bar clamps 35, 36,137 and 38 are located the similar clamps `42, 43, in which are slidably mounted the forward ends of leaf springs 44, .45. The rear end of each of the leaf f springs 44, 45 is mounted in a shackle 46,

which is secured tothe rearmost side bar `clamp 47, on which is mounted the rear cross bar 22 of the car body frame. A pair of lwheels 48 aresuitably mounted on shafts 49 and properly connected with the` drive and The axles are y blocks 52, which are clamped to the lea springs 44, 45.` The bearing blocks 52` are coupled" with the `axle `extensions 18, 19 of the driving mechanism by means of tie rods 53, 54, which `have turn buckles 55 for adjusting the location of axles 49, with respect to `axle extensions 18,19. The construction thus permits the frame itself to play upon` the springs 44, 45, while the car body plays upon `the frame, and at the same timethe tension upon the driving chainswis susceptible of adjustment.

` `I claim:` i i 1. A trailer car attachment for motor cycomprising` in combination a car body,

i specineatiqn of Letters Patent, 1 atented Jiily 1,1919. i

a frame, means for yieldingly connecting said carbody with said frame, a pair of wheels, means for yieldingly connecting said frame with said wheels and means for firmly securing said frame to the rear frame of a `motor cycle.

2. The combination with a motor cycle iio having its rear vvheel removed and provided with a chain drive, of A,a trailer car e body and frame having Wheels operatively connected With the chain drive of said niotQl1 cycle, means securely fixing said car body frame to Ithe yrear yfranfie of themotor cycle andinaintalning said motor cycle frame in a Uopiesn'of this patentrmay be obtained for having its rear wheel removed and provided With achain drive0f a trailer car body and frame having Wheels operatively connected `with fthe chain drive of said motor cycle,

ineans securely fixing said car body frame to the rear frame of the `motor cycle and maintaining Said motor cycle frame in a substantiall vertical plane, and means for trussing an reinforcing theframe adj acent to the driving mechanism of the motor cycle.
